Let's roll up our sleeves and solve this. We have 588 and we're going to multiply it by 9, essentially adding 588 to itself 9 times.
Step 1: 0 + 588 = 588
Step 2: 588 + 588 = 1176
Step 3: 1176 + 588 = 1764
Step 4: 1764 + 588 = 2352
Step 5: 2352 + 588 = 2940
Step 6: 2940 + 588 = 3528
Step 7: 3528 + 588 = 4116
Step 8: 4116 + 588 = 4704
Step 9: 4704 + 588 = 5292

So, 588*9 = 5292
